Take a close look at the image and note the critical component of the aircraft that could potentially come into contact with the leading edge of the other - the aileron. Again, wild speculation. For an aircraft to spectacularly depart controlled flight, short of a stall, it presumably has lost the ability to be controlled, and control comes from the elevator and ailerons.
